A complete JavaScript implementation is made up of the following three distinct parts: the core (ECMAScript), the document object model (DOM) and the browser object model. Web browsers are just one host environment in which an ECMAScript implementation may exist. A host environment provides the...
You’ve probably heard about ECMAScript 6 (or ES6) already. It’s the next version of JavaScript, and it has some great new features. The features have varying degrees of complexity and are useful in both simple scripts and complex applications.
"Strict mode" is a feature introduced in ECMAScript 5 (ES5) that allows you to write JavaScript code in a more disciplined and error-resistant manner. When you enable strict mode in your code, the JavaScript engine enforces a stricter set of rules and produces more helpful error messages, ...
